Dynamic Self-Checking Burner Controller Model: AUR455

The model AUR455 dynamic delf-checking burner controller compact design requires little installation space and can be used for continuous and batch operations. It follows the correct ignition sequence to automatically and safely ignite gas burners and oil burners. This device is compatible with model AUD300C advanced ultraviolet flame detector, model AUD500C explosion-proof advanced ultraviolet flame detector, or a flame rod. The model AUR455 drives the shutter built into model AUD300C / AUD500C to continuously check its flame detection circuit and the ultraviolet detector to provide flame detection for continuous burner operation. When used with a flame rod, the model AUR455 continuously checks its own built-in flame detection circuit to provide flame detection for continuous burner operation. The pilot ignition time can be selected from 4s or 8s. The ignition method can be selected from intermittent pilot and interrupted pilot.

The front connector provides a convenient communication function and event output for maintenance and troubleshooting. The PC loader can read various data types recorded in model AUR455 using the RS-485 communications protocol, including the flame voltage, ignition delay time, combustion count and combustion count of any sequence. The front 7-segment LED display shows the flame voltage and the current operating status. When an alarm is activated, the display indicates operating status, alarm codes, and event codes so the details can be checked easily.

The pilot Ignition time can be selected from 4 s or 8 s. To ensure timely replacement of the ultraviolet flame detector, the event function outputs a reminder after 25,000 hours of combustion use.

Wires connect to the sub-base, making the unit easy to install/remove. Flame monitor and alarm output contacts are available as independent non-voltage contacts. There are terminals for external reset inputs. This device can be reset from the operation panel.
